RICHARD L. HANGRUM AND ROLAND O. TOEVS, 0] LOS ANGELEB, CALIFORNIA.

Application filed June 88, 1828. Serial No. 647,219.

To all whom it may concern.

Be it known that we. RICHARD L. MAN- GRUM and ROLAND 0. Tours. citizensof the United States. residing at Los Angeles. in the county of LosAngeles and State of California. have jointly invented new and usefulImprovements in Tanks. of which the following is a specification.

Our invention relates to tanks and it is an improvement upon our tankdisclosed in our application for United States Letters Patent filedDecember 21. 1922, Serial No. 608.163. which tank is composed of aplurality of sections welded together and reinforced at their joints.providing a solid structural tank which is strong. durable, fluid tight.fire proof and economical in construction.

The main object of our invention is to provide improved reinforcingmeans at the oints between the sections. thus providing a stronger. moredurable and more eflicient tank than our former tank above mentioned, orany other known tank.

Other objects and advantages will appear hereinafter. and while we showherewith, and will describe a preferred form of construction. we desireto be understood that we do not limit ourselves to such referred form.but that various changes an adaptations may be made therein withoutdeparting from the spirit of our invention as hereinafter claimed.

Referrin to the drawing which forms a part of this specification:

Fig. 1 is a plan view of our tank.

Fig. 2 is a vertical transverse section of our tank taken on line 2-2 ofFig. 1.

Fig. 3 is an enlarged fragmentary vertical sectional view of our tankillustratin the joint for securing the cover to the body of the tank.

Fig. 4 is a fragmentary sectional view taken on line 4-4 of Fig. 2showing one of the vertical joints between the body sections.

Fig. 5 is a fragmentary sectional view taken on line 55 of Fig. 2showing the joint between the body and the bottom of the tank.

Fig. 6 is a view similar to Fig. 5 of a modified form of joint betweenthe body and bottom of the tank.

Fig. 7 is a view similar to Figs. 5 and 6 of another modified form ofjoint between the bottom and body of the tank.

In the drawing 1 indicates the bottom of my tank. 2 the body. and 3 thetop thereof. The bottom 1 is composed of a plurality of metal plates 4.5. 6 and T. the plates 4 and 5. the plates 4 and 6. and the plates 5 and7 being joined together at their meeting side edges by joints 8comprising upturned flanges 9 at said edges which flanges are weldedtogether at their upper edges as indicated at 10. The joint 8 unitingthe plates 4 and 5 extends diametrically of the bottom 1 and the jointsuniting the plates 4 and 6 and the plates 5 and 7 extending parallel tosaid diametrical joint uniting plates 4 and 5. The adjoining ends of theplates 4. the plates 5. the plates 6 and the plates 7 are also united byjoints 8. The construction of the top 3 is the same as the constructionof the bottom as above described and a detailed description of said topis therefore not necessary.

The body 2 is composed of a plurality of superimposed annular units ll.Each unit 11 comprises a plurality of arcuate plates 12 joined togetherat their vertical edges by joints 13. each of which joints comprisesoutturued flanges 14 on adjoining edges of said plates and a T-bar 15,the leg member 16 of said bar extending outwardly between said flangesand the head member 17 of said bar resting against the inside of saidplates 12. said leg member 16 of said T-har and the flanges 14 beingwelded together at their outer edges as at 18. and said head member 17of said T-har being spot welded to the inside of the plates 12 as at 19.The units 11 have formed at the lower and upper edges of the plates 12external annular flanges 20 and 21 respectively. The ends of the joints8 at the periphery of the bottom 1 are cut arm as at 22 to accommodatean annular ange iron 23. the base flange 24 of which an e iron beingexternal of its vertical flange 25 and said base flange resting uponsaid bottom with its outer peripheral ed e coinciding with theperipheral edge 0 said bottom. The lowermost unit 11 telescopes over thevertical flange 25 of angle iron 23 and the base flange 20 of said unitrests upon the base flange 24 of said angle iron with its outer edgecoinciding with the outer edge of said base flange 24 and the bottom 1.The outer edges of the bottom 1, flange 24 and said flange 20 are weldedtogether as indicated at 26 thus forming a most efi'ective reinforcedjoint 27 between the bottom 1 and the lowermost unit 11. The an le iron23 is spot welded at its upper e ge to the inside of the lowermost unit11 as at 28. The superimposed units 11 are united together by joints 30,each of which comprises the flange 21 of one unit, the flange 20 of theunit above, and an annular T-iron 31, the leg flange 32 of said T-ironbeing external of the vertical head flange 33 and extending between saidflanges 20 and 21, with said unit telescoped over said head flange. Theouter edges of said flan es 20, 21 and 32 coincide and are we] edtogether as indicated at 34, while the edges of the head flange 33 arespot welded to the inside of said units 11. as at 35. The joints 8between the bottom plates 4 and 5 are cut away at the center of thebottom 1 to receive a disk 36, which is welded to the inside of saidbottom centrally thereof. A post 37 extends centrally longitudinally ofthe tank and rests on and is welded at its lower end to the disk 36.

A disk 38 is welded on the upper end 'of post 37. The upper end of thepost 37 is centrally secured in position by radial angle bars 39. theinner and outer ends of the vertical flanges 40 of which bars being cutaway a short distance as at 41 and 42 respectively. so that the endportions of the upper horizontal flanges 43 of said angle irons restrespectively upon the disk 38 and the upper flange 21 of the uppermostunit 11, and are welded to said disk and said flange.

Arcu'ate angle irons 44 are placed between the outer ends of the angleirons 39 with their horizontal flanges 45. which. are external of theirvertical flanges 46, resting upon said flange 21 of said uppermost unit11 and with their vertical flanges 46 resting against the inside of saiduppermost unit. the outer edge of said flanges and 21 coinciding. Thecover 3 rests upon the flanges 45 of angle irons 44 and the flanges 43of angle bars 40 with the edge of said cover coinciding with the outeredges of flanges 45 and 21 and the outer ends of angle bars 39 and saidouter edge of said cover is welded to the outer edges of the flanges 45and 21 and to the outer ends of said angle bars and the outer edges 9fsaid flange 21 as indicated at 47, thus forming an etl'ective joint 48between said cover and the upper edge of the uppermost unit 11.

The angle irons 44 are spot welded at their lower edges to the inside ofsaid unit 11 as at 49 and at their corners to the under side of rover 3as at 50.

manhole 51 may be located in the side of the tank at the bottom thereof.Said manhole may consist of a box-shaped member 5:2 open at its innerend and fitted at said end within an opening 53 in the wall of thelowermost unit 11 and detachably closed at its outer end by a plate 54.which is bolted by bolts 55 to an external flange 56 on said outer end.An inturned flange 57 may be formed around the inside of the opening .33and the inner ends of the upper and side walls of the member 52 weldedto said flange 57. while the lower wall of said member may be welded tothe bottom 1.

A vertical ladder 60 may be located atone side of the tank. which laddermay be welded at its lower end to joint 27 and at its upper end to joint48. and braced intermediate its ends by braces 61 welded at their innerends to joints 30 and at their outer ends to the ladder.

In the modified form of joint 27 the flange 20 rests directly upon thebottom 1 and an annular angle iron 62 fits within the unit 11 with itsvertical flange 63 against the wall of said unit and its lowerhorizontal flange 64. which extends internally from said verticalflange. resting upon the bottom 1. The outer edges of the flange 20 andthe bottom 1 are welded together as indirated at 65. The edges of theflanges 63 and 64 of the angle. iron 62 are welded to the unit 11 andthe bottom 1 as at 66 and 67.

In the modified form of joint 27 shown in Fig. 7 an annular T-iron T0 issubstituted for the angle iron 23. the head member 71 of said angle ironresting upon the bottom 1 with its outer edge flush with the outer edgeof said bottom. and the unit 11 being telescoped over the verticalflange 72 of said T-iron with the flange 20 of said unit resting uponthe outer arm of the head member 71. with the outer edge of said flangecoinciding with the outer edge of said arm and the bottom 1. which outeredges are welded together as indicated at 73. The upper edge of themember 72 of the T-iron is spot welded at 74 to the inside of the unit11, while the inner edge of the head'member 71 of said T-iron is spotwelded to the bottom 1 as at 75.
